TWYER-IRON.

SPECIFICATION forming part of Letters Patent No. 787,868, dated April 18, 1905.

Application filed March 10 1903. Serial No. 147,050.

Be. it known that I, (inonsn A. VAL'IIGH. a

citizen of the United States, residing at Prescott, in the county of Pierce and State of 'isconsin, have invented certain new and useful Improvements in Twyer-lrons, of which the following is a specification.

My invention relates to improvements in twyer-irons for use in connection with blacksmiths" forges, its object being particularly to provide improvements in the iron for limiting the air-blast to a small space for heating small articles or to lengthen the line of flame for the purpose of heating longer articles, such as wagon-wheel tires.

My invention further consists in improved means for removing cinders and in other features of construction hereinafter particularly described and claimed.

.In the accompanying drawings, forming part of this specification, Figure 1 represents a top View of my improved twyer-iron. Fig.

is a section on line ,1 a of Fig. 1 looking toward the rear of the twyer-iron. Fig. 3 is a similar view looking toward the front of the twyer-iron. Fig. :t is a top view of the twyeriron with part of the ports closed, and Fig. 5 is a section on line y of Fig. 1 looking toward the center of the iron.

In the drawings, A represents the twyeriron casing, which, as shown, is conical and is formed upon one side with a neck 2, into which the bellows is intended to be fitted. The inner end of the neck flares, so as to spread the air as it enters the casing. In the top of the casing is a. large elliptical port 3, and on either side thereof are a series of smaller ports 4. The small end of the twyer-iron casing is closed, and the opposite end is left open to receive. the valve member B. The valve member is provided with an end wall 5, closing the end of the casing and carying a suitable handle 6. The valve member is curved to conform to the twyer-iron casing and is provided with a large poi-t7, which may be turned into registering position with the port 3. One side of the valve member is formed with openings 8. By means of the openings 8 the valve may be turned to close a part of the openings i and to partially close the opening 3, as

illustrated in Fig. t. The opposite side of the valve is formed with a central wing 12, by means of which the port 3 may be closed, leaving the openings 4: uncovered. ln order to prevent clinkers dropping through the openings 3 and 7 and also serve as a guide. the valve is formed with a central partition 9. The inner end of the valve is formed, as shown in Fig. 1, with a pair of inwardly-turned lips 10, which upon the valve being turned and withdrawn will assist in drawing out any clinkers or cinders which may have dropped into the twyer-iron casing.

In use the valve member is inserted in the twyer-iron casing, as shown the drawings. \Vhcn the valve member is turned to cause the port? to register with the port 3, the body of the valve will close the ports 4, limiting the blast to the port 3. When it is desired to get a full-length blast, as for heating wagon-tires, the valve may be turned to the opposite side of the casing, freeing all of the ports at and the port 3. By turning the valve to bring the wing 12 underneath the opening 3 said opening 3 will be closed and all of the ports a left open to restrict the blast to the openings et. By turning the valve into intermediate position, as shown in Fig. 4, the four end ports are entirely closed and the central port 3 partly closed. As shown in Fig. it, the openings 8 are of such length that when the valve is in the position shown in said ligure the wing 11 intermediate of the openings 8 will only partially cover the port 3.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A twyer-iron comprising a tubular casing provided with a relatively large central opening and a series of smaller openings on either side thereof, and a valve rotatably fitted within said casing and curved to conform thereto, said valve being formed with an opening to register with said large outlet-opening, and with openings to register with a portion of the smaller openings upon both sides of the large opening while said large opening is closed.

2. A twyer-iron comprising a conical casing provided with an inlet-opening and with a series of outlet-openings, a valve rotatably fitted Within said casing and curved to conform thereto, said valve being provided With an opening to register With the central one of said outlet-openings, and being provided upon one side With a Wing to close said central opening While leaving a portion of the remaining outlet-openings uncovered.

3. AtWyer-iron,comprisingatubular casing provided With inlet and outlet openings, a valve removably fitted in said casing, and inwardly-extending lips carried by the inner end of said valve, as and for the purpose set forth.

4:. Atwyeriron,comprisingatubular casing provided With an inlet-opening, and With an outlet-opening consisting of a central relatively large opening and smaller openings on either side thereof, and a valve fitted in said casing provided With a central partition, said valve being formed With an opening to register With said large outlet-opening, and With openings to register with apart of said smaller openings, said valve also being cut away to register with all of said outlet-openings in the rotation of said valve.

In testimony whereof I aflix my signature in presence of two Witnesses.

GEORGE A. WALTER.
